Centering Admin Bar (fixed width)

I created a theme, edited some stuff in header.php and footer.php putting them into the WP theme directory that I made for it. There are a few things I’m having issues figuring out how to edit, without going into the overwriting parts in the default.css, adminbar.css, reset.css, etc.

The buddypress/admin bar at the top. I am trying to get it to be centered like the rest of the page so that it has a fixed width, however I’m not having any luck. Anyone have any suggestions on what I can do?

Yeah that is what I put in it thinking that would override what was there. When I’m actually done it won’t be that wide but I needed a size that I could tell was actually doing something. However I think there is a !important tag for width already in default.css that may be contributing to the issue.

Originally I just did the edits the default, adminbar, style.css for BuddyPress. But the last update broke all the changes. So now I’m trying to do it through the child theme so it won’t break with a BP update.
